Abstract:
In contrast to an enolizable dimedone derivative, the non-enolizable 2-methyl-2-2-benzoyl ethyl-dimedone was cyclised to 1-methyl-4-phenyl bicyclo3,3,1non-3-en -8.9-dione. The infrared spectrum of this and other non-enolizable beta-diketones shows a split carbonyl band. This phenomenon was investigated. A new cycloheptene synthesis previously reported was applied to the synthesis of a compound related to the alkaloid colchicine. Author
